How did life begin on Earth? University of Chicago geophysicist Joseph V. Smith, in a Proceedings of the National Academy of Sciences paper, provides a theory for how small organic molecules may have been able to assemble on the surfaces of minerals into self-replicating biomolecules, the essential building blocks of life. |

According to a study, those born first to women younger than 25 are twice as likely to defy the average life span and go on to live beyond 100. Leonid A. Gavrilov and his colleagues at the University of Chicago's Center for Aging have relied on a wealth of Internet data, from genealogy Web sites to federal death indexes, to study centenarians to figure out why so many firstborns seem to outpace their younger siblings in the longevity race. |

University
: 14 June, 2007 |
Researchers at the University of Chicago have found that women prefer the scent of some men over other men because of genes they have inherited from their fathers. This is the first time scientists have demonstrated that people can actually inherit preferences, said Martha K. McClintock, the David Lee Shillinglaw Distinguished Service Professor in Psychology at the University, and the co-author of a paper that will be published in the journal Nature Genetics. |

Researchers find angiogenesis inhibitors effective in metastatic clear cell renal cell cancer treatment |

Professional Society
: 14 June, 2007 |
According to accumulating evidence, angiogenesis inhibitors can be far more effective in treating metastatic clear cell renal cell cancer, an aggressive form of the most common kind of kidney cancer that is also rich in blood supply, than traditional treatments. They can prolong life in about a third of patients, but researchers have not been able to identify the responding patients, prior to treatment. |

A University of Chicago-based research team reports in the Journal of Clinical Investigation that oral medications most widely used to lower blood-sugar levels in patients with type 2 diabetes are likely to increase the risk of spasm of the coronary arteries. Constricted arteries increase blood pressure and decrease blood flow to the heart, causing chest pain and even sudden death, shows the study, which focused on mice with a genetic defect that duplicates the actions of these drugs. |

Los Alamos National Laboratory researchers have developed a new method for the study of ion channel gating kinetics. An ion channel is a protein pore that lets ions (charged atoms such as calcium) pass through a cell's membrane. The method fits data to a new class of models, called manifest interconductance rank models, which will give researchers a better understanding of the mechanisms by which ion channels open and close. |
